Dropper device for controlled distribution of a make-up product

ABSTRACT

This invention relates to a dropper device including:
         a container,   a face makeup composition stored in the container, said face makeup cosmetic composition having a viscosity of less than 0.5 Pa·s, preferably less than 0.3 Pa·s, more preferably less than 0.2 Pa·s and even more preferably less than 0.1 Pa·s measured at 25° C.,   a closure member,   a pipette attached to the closure member, and   a compressible chamber linked to the pipette.

FIELD OF THE INVENTION

The purpose of the invention is distribution and application of face makeup compositions with low and even very low viscosity. More specifically, the invention relates to a dropper device for controlled distribution of a fluid face make-up composition with very low viscosity.

The dropper device of the invention is adapted for face make-up compositions having viscosity of, for example, less than 0.5 Pa·s at 25° C., preferably less than 0.3 Pa·s, in particular less than 0.2 Pa·s, and even preferably less than 0.1 Pa·s at 25° C.

BACKGROUND OF THE INVENTION

Foundations are commonly used to give the skin, in particular the face, color and an esthetic effect. These makeup products generally contain oils, pigments, fillers, and other cosmetic additives.

The consumers are increasingly looking for new face make-up compositions that can be spread easily and quickly on the skin in the form of a deposit that does not have to be thick, but that instead fuses as much as possible with the skin for a coverage with no trace nor mask effect. And they search for fluid and light galenics for thin film, easily to apply and with good comfort and wear properties (mattness wear, color wear, homogeneous deposit, non greasy nor sticky feeling).

However, the very low viscosity of composition makes them more difficult to distribute them easily and with a controlled manner. It is known sprays devices, tubes with tip made of foam, of fabric, of metal, tube with restricted end . . . .

And the challenge is important to find an adapted device for very fluid compositions, especially for a make-up composition which contains coloring materials, otherwise the result at the application is very dirty.

So it still remains a need for a new cosmetic product combining a specific device and fluid face make-up product with low viscosity (<0.5 Pa·s), even with a very low viscosity (<0.2 Pa·s at 25° C.).

The purpose of the invention is to satisfy these needs.

SUMMARY OF THE INVENTION

The applicant discovers that a specific dropper device with a pipette may answer these expectations. It permits to distribute a face make-up composition even with a very low viscosity (<0.2 Pa·s at 25° C. and even <0.1 Pa·s at 25° C.) with a controlled manner (drop by drop) for a non-dirty way of application. The face make-up composition when applied on the skin, fuses with the skin and allows tailor-made buildable coverage with no trace, covering imperfections and perfecting the complexion.

Thus, the invention relates to a dropper device comprising:

-   -   a container,     -   a face makeup composition stored in the container, said face         makeup cosmetic composition having a viscosity of less than 0.5         Pa·s, preferably less than 0.3 Pa·s, more preferably less than         0.2 Pa·s and even more preferably less than 0.1 Pa·s measured at         25° C.,     -   a closure member,     -   a pipette attached to the closure member, and     -   a compressible chamber linked to the pipette.

In a preferred embodiment, the face makeup cosmetic composition stored in the container has a viscosity of less than 0.1 Pa·s, preferably between 0.05 to 0.08 Pa·s measured at 25° C.

The viscosity of the composition is measured at 25° C. using a Rhéomat 180 (Lamy) fitted with an MS-R1, MS-R2, MS-R, MS-R4 or MS-R5 spindle, selected according to the consistency of the composition, which rotates at a speed of 200 rpm. The measurement is taken after rotation for 10 minutes. The viscosity measurements are carried out no later than 1 week after manufacture.

DESCRIPTION OF THE VIEWS OF THE DRAWING

FIG. 1 represents a longitudinal cross section view of a dropper device according to the present invention.

DETAILED DESCRIPTION OF THE INVENTION

By ‘controlled distribution’, it means a regular sequence of drops, opposite to an uncontrolled delivery by jet.

By ‘face make-up composition’, it means as examples a foundation, a perfector complexion, a BB or CC cream, and preferably foundation or perfector complexion.

Dropper Device

The face make-up composition of the invention is stored in a dropper device comprising a container, a closure member, a pipette attached to the closure member, and a compressible chamber linked to the pipette and configured to expel the product from the pipette when compressed and to suck the product into the pipette when relaxed. Such kind of dropper is also disclosed in WO0147784.

As an example shown at FIG. 1 which is a longitudinal cross section view of a device containing the face make-up composition of the present invention, a dropper device 1 for packaging and dispensing a product comprises a closure member 2 entirely screwed onto a container 3. The fluid make-up composition is stored in the container 3.

The container 3 comprises an housing extending along a longitudinal axis X, and a neck 4 defining the opening of the container 3. The neck 4 has a cross section smaller than the section of the housing formed in this container for containing the face make-up composition. A thread 5 is formed around this neck 4. The container 3 is made for example from glass, or from a thermoplastic material.

In a preferred embodiment, the container 3 is made from glass.

A wiper may advantageously be provided in the neck of the container in order to wipe the excess product deposit on the outside of the pipette when the pipette is withdrawn from the container.

In order to preserve the face make-up composition contained, the container 3 is closed off by the closure member 2.

The closure member 2 is provided locally on its inner periphery with a thread 6 that is intended to engage with a complementary thread 5 provided on the outer periphery of the neck 4 of the container 3. The closure member 2 is made for example from a thermoplastic material.

The closure member 2 is provided with a central opening which receives a pipette 7 in a tight seal manner. The pipette 7 may be made from glass.

Alternatively, the pipette 7 may be produced in one piece with the closure member 2. In this case the pipette 7 and the closure member 2 may be obtained by injection moulding of a thermoplastic material.

In a preferred embodiment, the pipette 7 is made from glass.

Preferably the pipette extends in a rectilinear manner. As a variant the free end of the pipette may extend obliquely.

When the closure member 2 is mounted on the container, the free end of the pipette 7 is dipped in the face make-up composition contained in the container 3. The free end may form a constriction 9 with respect to the internal cross section of the pipette 7 in order to limit the flow under gravity of the fluid in the pipette 7. The constriction makes it possible to retain face make-up composition by capillary action. The transversal cross section of the constriction is between 0.2 mm² to 3 mm², preferably from 0.5 mm² to 2 mm², more preferably from 0.8 mm² to 1.7 mm², more preferably from 1 mm² to 1.2 mm².

Preferably, the free end of the pipette has a conical form and not a spherical form. In a preferred embodiment, the free end of the pipette extends in a rectilinear manner and has a conical form.

The opposite end of the pipette is linked in a tight seal manner to a compressible chamber 8 outside the container. The compressible chamber 8 represented in FIG. 1 is a flexible bulb in a relaxed position. Alternatively the compressible chamber may be made with a piston linked to a push button.

When the free end of the pipette 7 is dipped into the face make-up composition, the movement of the compressible chamber 8 makes it possible to suck up fluid into the pipette 7. Then the pipette 7 may be removed from the container 3 and when the compressible chamber 8 is compressed, the face make-up composition contained is the pipette 7 is expelled.

The face make-up composition of the invention is not limited to be used with the dropper disclosed above but other actuating mechanism of dropper could be used. For example another actuating mechanism of dropper is disclosed in WO2011154397A1.

Procedure

The constituents of phases A1 and A2 are weighed into the main beaker and agitated, at ambient temperature, in the Moritz mixer (3500 rpm) for 15 minutes until homogenization.

Phase A3 is prepared separately by grinding three times, in a three-roll mill, the mixture of pigments, dimethicone copolyol and cyclohexasilixane.

This phase A3 is then added, while agitating, to the Moritz mixer (3500 rpm) for 10 minutes at ambient temperature.

Phase A4 is prepared separately by dispersing the KSP 100 in the mixture of the two oils, while agitating at ambient temperature, in the Rayneri mixer (500 rpm) for 10 minutes until homogenization.

This phase A4 is then added slowly, while agitating at ambient temperature, to the Moritz mixer and while increasing the agitation speed from 3500 rpm to 4000 rpm. It is then left to agitate for 10 minutes at 3500 rpm.

The Moritz agitation is then reduced to 1500 rpm and phases B and C are added while progressively increasing the agitation speed from 1500 to 2500 rpm. After incorporation, the mixture is left to agitate for 5 more minutes at ambient temperature at 2500 rpm and then quickly packaged.

The viscosity of the foundation was measured at 25° C. using a Rhéomat 180 (Lamy) fitted with an MS-R2 spindle, selected according to the very low viscosity of this foundation (very fluid), which rotates at a speed of 200 rpm. The measurement is taken after rotation for 10 minutes. The viscosity measurements are carried out no later than 1 week after manufacture.

We obtained a 15-18 UD (deviation unit) with the said MS-R2 spindle, corresponding to 60-80 cP (centiPoises), which correspond to 0.06-0.08 Pa·s.

Example 2 Evaluation and Selection of Devices

Several types of devices with different tips were tested with the said foundation. The results are presented hereunder:
